How to quickly cure itchiness

Hi, for the past 2 days I have been experiencing itchiness down there. It's not painful at all and is just basically itchiness that is sometimes extreme and sometimes only slightly. I think it may be a yeast or bacterial infection, although I am a virgin and didn't masturbate for like forever.

Anyways, the main problem here is that it's inconvenient to see a doctor here due to personal reasons, and I'm an athlete. The itchiness often affects my performance during training and I've got some events coming up, so is there any quick home based way I can get rid of the itchiness?

PS: I do clean it down there with water every day. No cleanliness issues.
